Answer:

b = 9

Step-by-step explanation:

Using Pythagoras' identity in the right triangle.

The square on the hypotenuse is equal to the sum of the squares on the other 2 sides, that is

b² + 12² = 15²

b² + 144 = 225 ( subtract 144 from both sides )

b² = 81 ( take the square root of both sides )

b = \sqrt{81} = 9

11. 180-73 = 107
10. 180-107=73
12. 180-73=107
13. 5x + 20 + B = 180 -> B = 180 - 20 - 5x and 3x+66 + B = 180 -> 3x+66+ (180 - 20 - 5x) = 180 ->  222-180 = 2x -> x = 21 
14. ABC = 5x + 20 = 5*21+20= 125
15. ABE = 3x+66 = 3*21+66 = 129

First right answer gets brainliest :)
Vsevolod [243]

Answer:

(2 1/4, 1 1/2) A

(-1 1/4, 1 1/2) B

(-2 1/2, 1/4) C

Step-by-step explanation:

We can determine that each tick mark represents 1/4 based off the given numbers. Now we just determine the points.

(2 1/4, 1 1/2) A

(-1 1/4, 1 1/2) B

(-2 1/2, 1/4) C

On average, Christopher scores 2 goals in a soccer game but, depending on how well the opposing team is playing, his goal total
SVETLANKA909090 [29]

Given:

Christopher scores 2 goals in a soccer game.

His goal total can vary from the average by 1 goal.

To find:

The absolute value equation can be used to calculate Christopher's maximum and minimum goals per game.

Solution:

Let Christopher scores x goals in a soccer game.

Then difference between actual goals and average goals is x-2.

His goal total can vary from the average by 1 goal.

Maximum number of goals = 2+1 = 3

Minimum number of goals = 2-1 = 1

It means, the difference between actual goals and average goals is either -1 and 1.

x-2=-1        ...(1)

x-2=1         ...(2)

Using (1) and (2),we get

|x-2|=1

Therefore, the correct option is C.
